I think the webtoon’s version is much better. It has a good start but then they changed the plot only because songkang casted as the main character just doesn’t make sense. Story pace is too slow, can’t watch it without fast forward everything.
And what’s the message they wanted to deliver to the young people? That you got to stay in the toxic relationship? That it’s okay to choose the manipulative guy? That good guy always win last?
The only positive thing in the series is the side characters’ story.
